refactor!: replace sys-systemctl with sys-service, add sys-daemon, and rename systemctl_* → system_service_* across repo

Browse Source 
- Swap role includes: sys-systemctl → sys-service in all roles
- Rename variables everywhere: systemctl_* → system_service_* (incl. systemctl_id → system_service_id)
- Templates: ExecStart now uses {{ system_service_script_exec }}; add optional RuntimeMaxSec via SYS_SERVICE_DEFAULT_RUNTIME
- Move SYS_SERVICE defaults into roles/sys-service/defaults (remove SYS_SERVICE_ALL_ENABLED & SYS_SERVICE_DEFAULT_STATE from group_vars/07_services.yml)
- Tidy group_vars/all/08_timer.yml formatting
- Introduce roles/sys-daemon:
  - default manager timeouts (timeouts.conf)
  - optional purge of /etc/systemd/system.conf.d
  - validation via systemd-analyze verify
  - handlers for daemon-reload & daemon-reexec
- Refactor sys-timer to system_service_* variables (docs and templates updated)
- Move filter_plugins/filetype.py under sys-service
- Update meta/README to point to official systemd docs
- Touch many roles (backup/cleanup/health/repair/certs/nginx/csp/wireguard/ssd-hdd/keyboard/update-docker/alarm compose/email/telegram/etc.) to new naming

BREAKING CHANGE:
- Role path/name change: use `sys-service` instead of `sys-systemctl`
- All `systemctl_*` vars are now `system_service_*` (e.g., on_calendar, state, timer_enabled, script_exec, id)
- If you have custom templates, adopt RuntimeMaxSec and new variable names

# Core Daemon Reset
# sys-daemon
## Description
This role resets and cleans up all **Infinito.Nexus** core daemon `systemd` service units that match the configured suffix (`SYS_SERVICE_SUFFIX`).
It is primarily used in maintenance or reset scenarios when a full service cleanup is required.
Role to reset and configure the **systemd manager** for Infinito.Nexus.
It ensures a clean state of the manager configuration and applies default timeout values.
## Overview
When the `MODE_RESET` flag is enabled, the role will:
1. **Run Once Per Play:** Guarded by `run_once_sys_daemon` to avoid duplicate execution.
2. **Identify Service Units:** Finds all `/etc/systemd/system/*{{ SYS_SERVICE_SUFFIX }}` units.
3. **Stop and Disable Services:** Gracefully stops and disables matching services.
4. **Remove Unit Files:** Deletes the corresponding unit files from the system.
5. **Reload systemd:** Ensures the service manager state is updated after cleanup.
## Purpose
The main goal of this role is to ensure a clean and consistent state for core daemon services by removing obsolete or stale systemd units.
This is particularly useful when re-deploying or performing a full environment reset.
- Purges the systemd manager drop-in directory if requested.
- Validates all active unit files before reload/reexec.
- Applies default timeout values for systemd manager behavior.
- Provides handler-based reload/reexec for systemd.
## Features
- **Automated Cleanup:** Stops, disables, and removes targeted systemd units.
- **Idempotent Execution:** Runs only once per playbook run.
- **Configurable Targeting:** Matches services using `SYS_SERVICE_SUFFIX`.
- **Systemd Integration:** Reloads daemon state after changes.
- **Drop-in Purge:** Optionally remove `/etc/systemd/system.conf.d` contents.
- **Manager Defaults:** Deploys custom timeouts via `timeouts.conf`.
- **Validation:** Uses `systemd-analyze verify` before reload.
- **Integration:** Triggers `daemon-reload` or `daemon-reexec` safely.
